This commit updates the tool-chain information, pointing at the versioned install path now. It also removes historic information that is no longer of interest.

Genode tool chain
|
|
=================
|
|
|
|
The Genode OS framework depends on the GNU C++ compiler and tool chain. As
|
|
most GNU compilers shipped with standard Linux distributions include
|
|
distro-specific patches and configurations, these tools do not meet Genode's
|
|
special requirements (e.g., thread-local storage configuration). Therefore,
|
|
there exists a special tool chain adapted to the specific requirements of
|
|
Genode.

Recommended development platform
|
|
################################
|
|
|
|
We use recent [https://www.ubuntu.com/ - Ubuntu] LTS releases on our
|
|
development hosts. Hence, Genode should always build without trouble on these
|
|
platforms.
|
|
|
|
|
|
Unified tool chain
|
|
##################
|
|
|
|
Starting with Genode version 11.11, there is a unified tool chain for all base
|
|
platforms and supported CPU architectures (x86_32, x86_64, ARM, AARCH64, and
|
|
RISC-V).
|
|
For Genode development, we highly recommend the use of the official Genode
|
|
tool chain. It can be obtained in two ways: as pre-compiled binaries or
|
|
manually compiled:
|
|
|
|
:Pre-compiled:
|
|
Our pre-compiled tool chain is runnable on Linux x86_32 and x86_64. The
|
|
archives for both versions will be extracted to
|
|
_/usr/local/genode/tool/<version>_.
|
|
To extract the archive, use the following command:
|
|
! sudo tar xPf genode-toolchain-<version>-<arch>.tar.xz
|
|
The use of the 'P' option ensures that the tool chain will be installed at
|
|
the correct absolute path where the build system expects it to reside by
|
|
default. Please note, Genode OS Framework releases require a Genode tool
|
|
chain with an equal or next smaller version number.
|
|

|
|
|
|
:Compile from source:
|
|
For those of you who prefer compiling the tool chain from source, we provide
|
|
a tool for downloading, building, and installing the Genode tool chain. You
|
|
find the tool in Genode's source tree at 'tool/tool_chain'. For usage
|
|
instructions, just start the tool without arguments.
|
|
|
|
In both cases, the tool chain is installed to _/usr/local/genode/tool/<version>_.
|
|
This install location is expected by the build system by default.
|
|
The tools are prefixed with 'genode-x86-', 'genode-arm-', 'genode-riscv-', or
|
|
'genode-aarch64-' respectively so that it is safe to add the
|
|
_/usr/local/genode/tool/<version>/bin/_ path to our 'PATH' environment
|
|
variable (optional).
|
|
|
|
Should you desire to use a different tool chain, create a file called
|
|
_tools.conf_ in the _etc/_ subdirectory of your build directory where you can
|
|
define the tool-chain prefix to be used:
|
|
|
|
! CROSS_DEV_PREFIX = /path/to/your/custom/tool_chain/your-x86-
|
|
